摘要：
The machining surface quality has an important influence on the meshing performance and life of non-circular gear transmission. According to the meshing principle of non-circular gear transmission, the coordinate system of non-circular gear tooth surface was established, and the tooth surface equation of non-circular gear was obtained. Combined with the tooth surface equation of non-circular gear, the cutting edge motion model of ball end milling cutter was established, and the milling locus equation of cutting edge under multiple factors was deduced. The surface topography of the non-circular gear was obtained by simulation calculation, and the influence of interval feed and feed per revolution on the residual height was analyzed. The non-circular gear solid parts were processed by five-axis CNC milling with a ball end milling cutter, and surface topography measurement experiment was carried out. The experimental results and simulation results were compared and analyzed. The analysis results show that the actual machined surface topography has a high coincidence with the theoretical simulation surface topography, which verifies the rationality of the theoretical method. This study has a certain guiding significance to improve the surface quality of non-circular gear in ball end milling.
